Clever code but pretty crap
I was impressed by the flat 3D engine running on Flash (who wasn't) but if you really did rob the engine from Flashkit I've kinda lost my respect for this. It certainly doesn't look very Wario- like, what with the realistic background and road. And as for the actual characters, they look like they were drawn in 5 seconds! Terrible! And there's no other karts or any game elements so what you're left with is an incredibly boring toy.
Either make this as a proper game with some suitable graphics or forget it.
